Designed to match the speed of high performance trading, Decibel offers spot, perpetuals, and yield products through a unified, self-custodial interface. The platform runs on the Aptos blockchain, leveraging its sub-20ms block times and parallel execution to support real-time settlement, cross-margining, and modular vault strategies.
